Intro: First grow, I did lots of research but ended up making a TON of mistakes in the beginning. Let's skip over that part, shall we? Here's the relevant info:
Plant: OG Kush Auto Feminized
Age: 30 days
Soil: random organic plant soil. Yeah, I know... but here we are.
Light: 100W full spectrum LED
Light schedule: 18/6
Space is small, 50x50x100, just enough for one plant.
Exhaust and a small fan inside are always on. Small one is not pointed directly at the plant.
Watering: Somewhat irregular, I was told I watered too frequently - every 24 hours with approx 300-500ml of water.
Water: tap water. I let it stay for 24 hours, but... it turns out somebody else in the household was using it and refilling my bottle. So it was just tap water.
The tap water created issues: top layer of dirt got mineralized to hell - it became white and rocky, probably causing excess calcium, which in turn probably increased PH (the soil already has a PH of 6-7).
Removed the top layer gently and replaced with fresh soil.
Issues in the first 2 weeks that I corrected:
The above issues were corrected approx. 11 days ago.
In the past 3 days, the plant grew by around 4 cm and seemed healthy.
Now, orange/brown tips appeared, and overnight also appeared on two of the latest leaves.
Bottom leaves are turning rather pale.
I suspect phosphorus and maybe potassium defficiency, combined with calcium overdose (due to tap water) and also probably ph issues. Plus the watering schedule.
Because this soil contains nutrients for approx. 4 weeks, I did not feed it anything so far.
Here's the plan: I have a good quality bio organic fertilizer with a NPK of 2-7-4, intended for flowering. This plant has entered flowering already (it's an auto, should be ready from seed to harvest within 10 weeks, so this is about the correct timing).
Recommended amount is 3ml/1 L of water at week 4. I plan on giving it 1ML of nutes with 500 ml of distilled water, after watering it 36+ hours ago.
Thoughts? Advice? Please keep in mind this is my first time and I don't really know what I'm doing, if it wasn't obvious.
Thank you so much!

Issues in the first 2 weeks that I corrected:
- Light burn (the ligth was way too close at 100%... it was like 40cm from the plant. Ugh.
- Heat burn - before I controlled temps, they were reaching more than 32 C. This caused leaves to curl up and grow weird and distorted. After fixing, new growth was normal.
- Low humidity - in the first 1.5 weeks, it was very difficult to control, and often went below 40%. Now I do my best to keep it above 55%.
- Red stems - I thought this is due to genetics, but after fixing above issues, stems turned green...
